Abstract

The biogas production potential of abattoir waste at different retention time was investigated and the bacteria associated with the production as well as the pH of the slurry before and after the biogas production was determined. The result revealed the presence of Bacillus megaterium, Bacillus licheniformis, Bacillus pumilus, Bacillus brovis, Bacillus alvei, Bacillus lentus, Yersinia enterocolitica, Proteus vulgaris, Escherichia coli, Pseudomonas aeruginosa, Staphylococcus aureus and Salmonella sp from the  spent slurry.  It also indicated a slight shift from a neutral medium to a slightly acidic environment in all the digesters. The highest volume of biogas (2240cm3) was obtained  in week 2 while the least volume (1820cm3) was obtained in week 4.Significant difference (p < 0.05) was observed in the volume of biogas produced in the first and second week as well as to that of third and fourth week. However, no such difference (p < 0.05)  was observed in the volume of biogas produced in the third and fourth weeks.
